During stops 34 thereon against the necks 32 on the members I6, as shown on Figure 1'. pin 28 being in engagement with the top edges this normal position of the assembly', the ñnger 41 on the brake lever arm 5 is behind the roller of the cam rails 9 at the rear ends thereof. The 49 between the lugs 26 so that, should the brake cam roller 42 on the acceleration control lever 4I is near the rounded corner of the cam lug 24 60 lever spring 45 break or become detached, the brake lever will be held from swinging down. and when the foot pedal is rocked rearwardly, Also during such normal condition of the as i. e., to the left as shown in Figure l as indicated by the dotted lines, Fig. l, the acceleration lever 4| will swing on the pin I8 to be operated for opening of the throttle valve for the desired ac celeration. During swing of the foot pedal for sembly, the force of the spring 43 will hold cam roller 42 against the cam lug 24 to hold the foot 65 pedal swung rearwardly with the forward roll ers 34 on the lug 25 in engagement with the front sides of the necks 32 of the guide members I6. Furthermore, the roller 49 by being in front of the brake lever finger 41 will lock the brake lever between the lower floor board 3 and the lever 4I and when the foot pedal is released, the spring 70 against operation while the foot pedal is being operated for acceleration control. will rock the lever back for return thereby of When it is now desired to brake, direct forwarc'A the pedal to normal position. During rocking of pressure is exerted by the entire foot against the the lever 4I on the fulcrum pin I8 the end of the foot pedal for bodily movement thereof.
